Abstract
The utility model provides a floating boring head which is located between a machine tool spindle and a boring rod. The floating boring head comprises a boring head body. The boring head body is coaxially connected with a half shaft through a crosshead shoe. The crosshead shoe is provided with a base part. A first protruding shoulder and a second protruding shoulder are arranged on the opposite surfaces of the base part respectively and of a cross shape on the base part. A groove is formed in the left end portion of the half shaft. The first protruding shoulder is in clearance fit in the groove. A matching groove is formed in the boring head body. The second protruding shoulder is in clearance fit in the matching groove. The crosshead shoe slides along the groove, so that deviation between the two shafts can be compensated when the spindle and a shaft sleeve are installed and operated, and the distortion phenomenon is eliminated. The crosshead shoe is used for transmitting axial motion, compared with the mode that a universal joint is mainly used for transmitting torque, machining accuracy can be improved, and the application range of workpieces can not be limited.
Description
Technical field
The utility model relates to a kind of machined components, particularly a kind of unsteady boring head.
Background technology
In the boring process, when the pitch-row of workpiece to be machined is larger, often adopt the processing method of guided bearing before and after boring bar.Sometimes because of main shaft and the bushing center line inconsistent, will produce " other strength " phenomenon, affect machining accuracy.And guided bearing method before and after adopting adds man-hour large due to pitch-row, more easily " other strength ".Therefore before and after adopting, the guided bearing method adds man-hour, all adopts floating connection between machine tool chief axis and boring bar.The floating connection method is a lot, often adopts and fill the mode of a universal joint between machine tool chief axis and boring bar at present, realizes floating connection.The employing universal joint connects, have the following disadvantages: 1) universal joint transferring power and when motion, allow between centers to have angle, affect transmission accuracy and then affect machining accuracy, 2) because universal joint is mainly used in transmitting torque, generally do not transmit axially-movable, making to transmit axially-movable can only bearing tension, cause workpiece to do feed motion towards a direction, limited range of application.

As preferably, this boring head body has conical nose and afterbody, and this conical nose inserts in the taper hole of machine tool chief axis, and this afterbody is offered shoulder hole, is provided with above-mentioned crosshead shoe and semiaxis in shoulder hole.
As preferably, above-mentioned mating groove is positioned at the left part of shoulder hole.
As preferably, this unsteady boring head further comprises two springs, and this semiaxis is offered respectively a blind hole in the both sides of groove, and spring is positioned at blind hole, and the base portion of butt crosshead shoe.
As preferably, this unsteady boring head further comprises the end cap that coaxially is connected in semiaxis.
As preferably, described end cap is fixed on the boring head body by screw.
As preferably, this unsteady boring head further comprises the adjustment ring that coaxially is connected in semiaxis.
As preferably, adjustment ring is presented axially between boring head body and end cap.
As preferably, this unsteady boring head further comprises two bearings that coaxially are connected in semiaxis.
As preferably, bearing is diametrically between boring head body and semiaxis.
The utility model compared with prior art, there is following advantage: slide along groove by crosshead shoe, the skew of two between centers in the time of can compensating main shaft and axle sleeve installation and running, eliminate other strength phenomenon, because crosshead shoe is used for transmitting axially-movable, be mainly used to transmitting torque than universal joint, not only can improve machining accuracy but also can not limit the range of application of workpiece.
The utility model is because there is centrifugal intertia force in crosshead shoe bias, so correct the eccentric position of crosshead shoe by adding shock mount, spring also available buffer impacts, absorbing vibration.
End cap of the present utility model can be limited to crosshead shoe and semiaxis in the boring head body.
Adjustment ring of the present utility model and bearing not only can be in order to the axial limitings of semiaxis, also can be in order to the gap between adjustment component, spring force during assembling, and can be in order to the compensate for wear displacement during use.
